Spoiler Alert:
Great movie, at times there were scenes that just changed the subject like after a quick cutaway to another setting for some reason. I also think they should have made William Afton slightly less crazy like his voice lines match the character but Matthew Lillard's voice for William should sound a little deeper and a bit darker.
Not much to say about the plot I have no problems with it.
The dialogue was great because it felt the character's were just talking normally but the dialogue towards the end of the film was kind of cliché.
Overall great film, I'm so happy one of my favourite games as a kid finally becomes a movie.
